ABSTRACT:
A method and system for securing an anchor in a hard substance or rigid material include a cutter bit for drilling a hole in the hard substance, an anchor for fitting within the drilled hole, the process of drilling the hole using the cutter bit, the drilling machine for using the cutter bit, and the resulting improved hard substance or rigid material that may be used as a curtain wall for fastening to a building or similar structure. The hard substance may be a sheet of granite, marble, glass, limestone, or other similar material. The invention includes an anchor that has a cylindrical shaft, a bevelled head portion, and an expanding collar for fitting within and securing the anchor in a drilled hole of the hard substance. The drilled hole includes a bevelled bottom portion that receives the bevelled head portion of the anchor and the expanding collar. A placement device transmits an impacting force to place the expanding collar around the bevelled head portion of the anchor. This secures the anchor in the drilled hole in a time-saving and highly reliable manner.
